chokidar 3.x has fsevents `^2.0.6` [as a dependency][dependency], which introduced node v12.x compatibility, a sought-after goal of our PR 1638. However, fsevents `2.0.6` node compatibility range is quite [complicated][complicated]. After fsevents `2.0.6` was published its maintainers published `1.2.9`, which backports NodeJS v12.x compatibility minus some performance increases, while offering [much more straightforward][straightforward] node compatibility. fsevents `1.2.9` [is compatible][compatible] with the latest v2.x release of chokidar (`2.1.6`). Since Embark advertises runtime compatibility with node `>=8.11.3`, downgrade chokidar to `2.1.6`.

What is Embark
Embark is a framework that allows you to easily develop and deploy Decentralized Applications (DApps).
A Decentralized Application is a serverless html5 application that uses one or more decentralized technologies.
Embark currently integrates with EVM blockchains (Ethereum), Decentralized Storages (IPFS), and Decentralized communication platforms (Whisper and Orbit). Swarm is supported for deployment.
With Embark you can:
Blockchain (Ethereum)
- Automatically deploy contracts and make them available in your JS code. Embark watches for changes, and if you update a contract, Embark will automatically redeploy the contracts (if needed) and the dapp.
- Contracts are available in JS with Promises.
- Do Test Driven Development with Contracts using Javascript.
- Keep track of deployed contracts; deploy only when truly needed.
- Manage different chains (e.g testnet, private net, livenet)
- Easily manage complex systems of interdependent contracts.
Decentralized Storage (IPFS, Swarm)
- Easily Store & Retrieve Data on the DApp through EmbarkJS. Including uploading and retrieving files.
- Deploy the full application to IPFS or Swarm.
- Import and deploy contracts hosted on Swarm.
Decentralized Communication (Whisper, Orbit)
- Easily send/receive messages through channels in P2P through Whisper or Orbit.
Web Technologies
- Integrate with any web technology including React, Foundation, etc..
- Use any build pipeline or tool you wish, including grunt, gulp and webpack.
